Hello, recently I updated my system again after a while (1-2 weeks) and I noticed that there was a grub discussion going on again with some issues. I updated my system like always and followed the two steps which were shown to me on the terminal which recommended running both grub installation and generation of configuration, so I did. I did not immediately reboot after this and went on my way for a few days again and choose to do another update, this time I rebooted into the following screen.
I tried opening the UEFI firmware settings but end up on a black screen which won’t load anything. I tried booting from my USB into endeavour os, so I could try out the same procedure with the problem grub had in August/September, but I can’t even do that it seem because I always end up with a black screen or on the screenshot I sent.
I would greatly appreciate any help or ideas on how to solve this issue, thank you very much.
You don’t rename the file there anyway. Are you able to boot on a live ISO? If so can you post this
Edit: What are you doing booting on the ISO because it requires arch-chroot. You have to mount the / partition and then mount the /efi partition and the arch-chroot to /mnt using the proper device names of course.
If you arch-chroot from the live ISO you could do grub-install and then run sudo grub-mkconfig -o /boot/grub/grub.cfg
Edit2: I can walk you through the arch-chroot if you post the output for lsblk -fm
I’ve installed the endeavour os onto an USB per the instructions with Rufus to try to boot into the live usb environment. But it just doesn’t seem to want to boot into it. I am either left on a blank black screen or the screenshot I sent earlier.
I tried this now, and sadly it didn’t work either, it just seems to be completely unresponsive once it tries to boot into the UEFI Firmware settings. That’s where the blank screen occurs. I can record a video of my steps if that would help solve this, but so far it’s always been:
Boot up laptop.
Grub boot selection screen → There is only one entry (uefi firmware settings)
Select it and boot into it
Blank screen. (unresponsive)
I want to add that before this issue, endeavour os was an entry in the grub selection, but after I updated and rebooted they were simply gone.
